- Zero Power (Zero Power) communication uses energy harvesting and backscatter communication technology.
- the zero-power communication system consists of network devices and zero-power terminals, as shown in Figure 2.
- the network device is used to send an energy supply signal (that is, a radio wave) and a downlink communication signal to the zero-power terminal, and receive backscattered signals from the zero-power terminal.
- the zero-power terminal includes an energy harvesting module, a backscatter communication module, and a low-power computing module.
- the zero-power consumption terminal may also be equipped with memory and/or sensors, the memory is used to store some basic information (such as item identification, etc.), and the sensor is used to obtain sensing data such as ambient temperature and ambient humidity.
- FIG 3 is a schematic diagram of energy harvesting.
- the energy harvesting module realizes the collection of space electromagnetic wave energy based on the principle of electromagnetic induction, and then obtains the energy required to drive the zero-power consumption terminal to drive the load circuit (such as drivers for low-power computing modules, sensors, etc.). Therefore, the zero-power terminal does not need a traditional battery, and realizes battery-free communication.
- the energy collection module refers to a radio frequency energy collection module, and the radio frequency energy collection module can collect energy carried by radio waves in space to realize the collection of space electromagnetic wave energy.
- Figure 4 is a schematic diagram of backscatter communication.
- the zero-power terminal receives the wireless signal sent by the network device (that is, the carrier wave in Figure 4), and modulates the wireless signal, that is, loads the wireless signal on the wireless signal.
- the information that needs to be sent and the modulated signal is radiated from the antenna. This information transmission process is called backscatter communication.
- load modulation is a method often used by zero-power terminals to load information.
- Load modulation adjusts and controls the circuit parameters of the oscillation circuit of the zero-power terminal according to the beat of the data flow, so that the magnitude and/or phase of the impedance of the zero-power terminal changes accordingly, thereby completing the modulation process.
- the load modulation technology mainly includes resistive load modulation and capacitive load modulation.
- a resistor is connected in parallel with the load, which is called a load modulation resistor.
- the resistor is turned on or off based on the control of the binary data flow.
- Amplitude keying modulation ASK
- signal modulation is realized by adjusting the amplitude of the backscattered signal of the zero-power terminal.
- capacitive load modulation a capacitor is connected in parallel with the load, which is called a load modulation capacitor. This capacitor replaces the load modulation resistor in Figure 5.
- the circuit resonant frequency can be changed by switching the capacitor on and off, thus realizing frequency keying modulation.
- (FSK) that is, the modulation of the signal is realized by adjusting the working frequency of the backscattered signal of the zero-power terminal.
- the zero-power terminal performs information modulation on the incoming signal by means of load modulation, thereby realizing the backscatter communication process. Therefore, the zero-power terminal has the following significant advantages: On the one hand, the zero-power terminal does not actively transmit signals, so it does not require complex radio frequency links, such as power amplifiers and radio frequency filters. On the other hand, zero-power terminals do not need to actively generate high-frequency signals, so high-frequency crystal oscillators are not required. On the other hand, the zero-power terminal communicates through backscattering, and the transmission process does not need to consume the energy of the zero-power terminal itself.
- the data transmitted by the zero-power terminal can use different forms of codes to represent binary "1" and "0".
- Radio frequency identification systems usually use one of the following encoding methods: reverse non-return zero (NRZ) encoding, Manchester encoding, unipolar RZ encoding, differential biphase ( DBP) coding, Miller coding, and differential coding.
- NRZ reverse non-return zero
- DBP differential biphase
- Using different forms of codes to represent binary "1” and "0” can also be understood as representing 0 and 1 with different pulse signals.
- the reverse non-return-to-zero encoding uses a high level to represent a binary "1”, and a low level to represent a binary "0", as shown in Figure 6.
- Manchester encoding is also known as Split-Phase Coding.
- the value of a certain bit is represented by the change (rise/fall) of the level during half a bit period within the bit length, and a negative transition during half a bit period represents a binary "1".
- a positive transition at half a bit period represents a binary "0", as shown in Figure 7.
- Manchester encoding is usually used for data transmission from a zero-power terminal to a network device when carrier load modulation or backscatter modulation is used, because it is beneficial to discover errors in data transmission. This is because the "no change" state is not allowed within the bit length. When the data bits sent by multiple zero-power terminals at the same time have different values, the rising and falling edges of the reception cancel each other out, resulting in an uninterrupted carrier signal within the entire bit length. Since this state is not allowed, the network device uses This error can determine the specific location of the collision.
- the high level of the unipolar return-to-zero code in the first half bit period represents a binary "1", and the low level signal that lasts for the entire bit period represents a binary "0", as shown in Figure 8.
- Unipolar return-to-zero coding can be used to extract bit synchronization signals.
- Any edge of the differential biphase encoding in half a bit period represents a binary "0", and no edge is a binary "1", as shown in FIG. 9 .
- the levels are inverted at the beginning of each bit period. Therefore, bit beats are relatively easy to reconstruct for the receiving end.
- Any edge of the Miller code in half a bit period represents a binary "1", and a constant level in the next bit period represents a binary "0".
- a level transition occurs at the beginning of a bit period, as shown in Figure 10. Thus, bit beats are easier for the receiver to reconstruct.
- each binary "1" to be transmitted causes a change in signal level, whereas for a binary "0" the signal level remains unchanged.
- zero-power terminals can be divided into the following types:
- the zero-power terminal does not need a built-in battery.
- the zero-power terminal When the zero-power terminal is close to the network device, the zero-power terminal is within the near-field range formed by the antenna radiation of the network device. Therefore, the antenna of the zero-power terminal generates an induced current through electromagnetic induction.
- the current drives the low-power computing module (that is, the low-power chip circuit) of the zero-power terminal to work, to realize the demodulation of the forward link signal and the signal modulation of the backward link.
- the zero-power terminal uses the backscatter implementation to transmit signals.
- the passive zero-power terminal does not need a built-in battery to drive it, whether it is a forward link or a reverse link, and is a real zero-power terminal.
- the radio frequency circuit and baseband circuit of the passive zero-power terminal are very simple, such as no low-noise amplifier (LNA), power amplifier (PA), crystal oscillator, ADC, etc., so It has many advantages such as small size, light weight, cheap price and long service life.
